From the perspective of dermatologists, this book explains the language of the skin to readers in a popular science language. For example, if the amount of sebum secreted is small, the skin is relatively dry and prone to fine wrinkles. The capillaries are shallow and easily broken, and the skin is relatively sensitive to external stimuli, which is dry skin; if the skin color is darker, the pores are large, the amount of sebum secreted is large, the skin is oily and shiny, it is not easy to wrinkle, and it is not sensitive to external stimuli, which is oily skin; if the amount of sebum secreted is moderate, the skin is neither dry nor oily, and it is ruddy, delicate, elastic, with small pores, and insensitive to external stimuli, it is neutral skin, etc.
本书从皮肤科专家的视角，以科普的语言向读者解读了肌肤的语言，如，皮脂分泌量少，比较干燥，容易生细小皱纹。毛细血管表浅，易破裂，对外界刺激比较敏感，是干性肌肤；肤色较深，毛孔粗大，皮脂分泌量多，皮肤油腻光亮，不容易起皱纹，对外界刺激不敏感，是油性肌肤；皮脂分泌量适中，既不干也不油，红润细腻，富有弹性，毛孔较小，对外界刺激不敏感，是中性肌肤等。
